JM Multi was established in March 2008 as JM Eco-Construction, renamed to JM Multi in 2015, and listed on the Korea New Exchange (KONEX) in 2021.
Its core business is the natural wood deck-road system, covering eco-friendly walking trails, barrier-free deck roads, and wooden footbridges for leisure and cultural spaces; as of the 2025 fiscal reference, product sales account for approximately 90% of total revenue and other revenues for the remaining 10%.
Through its in-house R&D center, the company has developed differentiated technologies including safety railings, filled square pipe systems, urethane mats, and eco-coating systems, and holds competitive positions in public procurement through MAS registration, Excellent Procurement Product designation, and quality certifications including ISO9001 and ISO14001.
Headquartered in Gongju, South Chungcheong Province, with an office in Seoul's Yeongdeungpo district, the company employs approximately eight staff as of June 2025, a 20% year-over-year decline, and holds eleven patents.
The deck-road segment faces structural competitive pressure from low entry barriers, a challenge the company explicitly acknowledged at an investor briefing, citing intensifying competition and the need for portfolio diversification.
In response, the company is expanding into cliffside walkway structures (jando) along mountain and coastal cliff faces, radar sensor-based smart healthcare solutions, and social welfare services through its subsidiary PeopleMulti, which focuses on elderly disability care.
An equity investment of approximately KRW 1 billion for a 5.26% stake in mobile gaming startup Pluppy Duck further signals portfolio diversification ambitions, though revenue contributions from these new ventures have not yet been confirmed.
The company's official website now lists radar sensor technology and smart healthcare solutions alongside its traditional deck-road business, reflecting a deliberate pivot intent.
